🧭 Description
This section automates Gmail message handling through AI-powered classification and response. Using the LangChain Text Classifier, incoming emails are analyzed and sorted into four categories — High Priority, Advertisement, Inquiry, and Finance/Billing — each triggering a dedicated action flow.
High Priority: AI generates a professional draft reply and saves it to Gmail.
Advertisement: AI summarizes content and logs it to Google Sheets.
Inquiry: AI composes a customer-friendly response automatically.
Finance/Billing: AI creates a brief summary and forwards it to the accounting email.
This system reduces manual sorting, ensures consistent communication quality, and speeds up email management with full automation.
